Question

Hi,
I am trying to use MYSQL with J2EESDK 1.4. I have create a simple CMP bean. When i try to deploy i get the following error.
JDO7001: Cannot find resource com/sun/jdo/spi/persistence/generator/database/MYSQL.properties. I wonder if this is related to
mysql.properties=dbType\=mysqlin my database.properties file. I am not sure what has to be given but the default pointbase has
pointbase.properties=dbType\=pointbaseThanx for all your help.

Hi,
I was having the exact same problem , and I am using mysql as well.
the error was:
JDO7001: Cannot find resource com/sun/jdo/spi/persistence/generator/database/MYSQL.properties.
I think I have solved my problem. It turned out that I had not saved my CMP mappings (from entity bean to database) .
open your EAR (or Jar) in the deploy tool.
click on a jar that contains entity beans and switch to the "general" tab for that bean
in the main window, open the "META-INF" link... you should see a file called
"sun-cmp-mappings.xml"
This file must exist for every jar contaning entity beans - it contains the cmp to database mappings.
If its not there for a given jar (one that contains entity beans, that is), then look at the general tab for each entity bean and select "sun-specific settings"
In the window that opens, switch the view pull-down to CMP-DATABASE. This is where you map your cmp feilds to database fields.
note that you must first map the database schema for your databases (see chapter 22 of the j2ee tutorial) before you can map the feilds, then add the database schema to your JAR that contains the entity beans.
Be sure to SAVE after you map!
